TOPAZ is a hybrid dry cooler with adiabatic precooling that dissipates the heat energy dry into the atmosphere. Without water treatment and without spraying water into the air flow, the coolant is cooled down to temperatures that are lower than the ambient air temperature. If the outside temperature rises, the humidification is switched on. With ambient air temperatures of up to ca. 23°C, the dissipation of heat is made by dry cooling. Bacteriological growth and pollution, as well as deposits in the heat exchanger are here prevented by the daily draining off the humidification water and the drying of the humidifier. The energy-saving motor and the low water consumption by recirculation also contribute to the low operating costs. The simple access through a rollup door and the parallel, vertical arrangement of the heat exchangers make servicing possible without dismantling the motors and fans.
